The Avatar of Mischief is one of the harder avatars to deal with due to his cloak of Mischief ability. This buff on him has a chance to proc a random status impairment on whoever hits him. Like other avatars he has a very nasty knockback which can send people flying. Some people prefer to tank him in the little pond which has the nightbloods circling around it.

Whever you decide to tank him in rivervale be prepared to deal with the stun, stifle, mezz, and other random impairments of is Cloak of Mischief ability.
